6. MPEG-2/MPEG-4 DVB Decoder – NEC EMMA3SL
6.1. General Description
The MC-10085/86/87/88 devices, EMMA3SL/HD, are part of the third generation of
multimedia processors based on NEC’s Enhanced MultiMedia Architecture (EMMA™). This
device provides nearly all the functionality required to realise a high performance and cost-
effective integrated digital TV.
NEC EMMA3SL integrates the functions of a TS de-multiplexer, a DMA controller, MPEG2,
H.264 (MPEG-4 part 10) and VC-1 video decoders, an audio processor, graphics and display
engines, a video encoder and DAC, and various interfaces to support peripheral modules.
The device has been designed with a memory interface using glueless logic which supports
DDR2 SDRAM. The MC-10085/86/87/88 incorporate a processor, two main buses and a
peripherals bus. The processor is a MIPS32 24KEc core and can access all modules within the
device.
